More Arsat 30/3.5 - Velvia

Here are some more Arsat images. A couple of them are sharpened,
just to see how well USM works on the Velvia scan from the Arsat.

Still experimenting, trying to see if the Arsat is a truly decent lens. So
far, it seems to be a keeper, but time will tell. All of these have some
degree of Photoshop processing.

These look great Larry
+1 on #1 Wink

Is there really snow up there already?
Man I'm looking at Baker and there is no new on the "Flanks" yet.
It's just a matter of time though I guess.

The Arsat looks the real Deal. Congrats!

Well said, I did not know how to explain my thought. Confused

Thanks you guys! Actually, the image #1 was cropped from the bottom
as well. The vertical wide-angle is huge.

Andy, yes this was the first snow of October, about 3 weeks ago. I
was on my way to a 9 day hike.

The Velvia really brought out the tones in image #3 - this was, to me, a
great place for the saturation of Velvia, especially in the golden-red
tones. The leaves are spot-on to what I saw, the tones against the blue-
green water mesmerized me.

Beautiful.

Two first would be nice in large size on a wall.

Nice stuff. What is the sharpness like with this lens, especially at the corners?


PostPosted: Wed Oct 28, 2009 5:26 pm    Post subject: Reply with quote

Nr.1, for my taste the strongest shot I have seen here in the forum since long time ... breathtaking indeed.

I also like the 3rd shot, the strange colorization makes it very appealing.

Cheers
Tobias

Thanks all of you! Funny, this was just to show the characteristics of
the Arsat, and a way to find out whether or not the lens is worth keeping.

Regarding the corner sharpness, #2 is an intense crop taken from the
lower right corner of an original. There IS some degradation
of sharpness in the corner, but as you can see, it seems to be
acceptable (at least to me).

Different types of shots can degrade or enhance the corner
sharpness depending on the subject matter. But overall I don't
think it is worse than any other super-wide.

Here is another corner crop, only about 1/3 cropped away this
time. You can see softer areas in the corners, but I don't think
it's all that bad. And I think that the overall propensity to do well
on shadows and highlights does say a lot for this lens.

So I just got myself an Arsat 30/3.5 and instead of making a whole new thread, I thought I'd just add it to the great thread Laurence started.






All with my problematic Kiev-6C + Arsat 30/3.5 + Fuji Provia 100F



In a word, I really like this lens. I've heard there are QA issues, but this appears to be a very good copy in that case, and definitely worth the $150 I paid for it, and then some Smile

Excellent results and very good metering. Love the bee and flower shot,
which handily obscures the barrel distortion. Provia colors!

i have been wanting to try this lens on my p6, but have not found a reasonably priced one. i am very new to medium format-i am still in the process of fixing my p6, but i love all these photos. i am very curious however at the fisheye effect i see in rawheads photos. i do not understand how a 30mm focal length can produce this effect? i routinely shoot 21mm-28mm and do not get this effect on ff 5d. how is this the case?
thanks for reply!

Well there are several things at play; one, a 30mm lens on a 6x6 medium format (56mm x 56mm) is much "wider" than 21mm on FF, closer to 15-16mm on FF, so any edge distortion will be much more obvious.

But much more importantly, lens design is very different; you are using rectilinear lenses which do all that they can to correct all those distortions; fisheye lenses don't even try. In fact it's encouraged Smile

And as a consequence, as the final difference, you get a much wider field of view with a fisheye design than you would with a rectilinear design.

For example, on FF, you can get a 16mm fisheye lens (e.g., Zenitar) that has a 180˚ FOV from corner to corner; that is much wider FOV than you would get with a 16mm rectilinear lens, which will have something like a 100˚ FOV if I remember correctly (maybe even less).

So in sum, my 30mm is on a larger format and is designed differently from your superwides.

As you can see, being a bokeholic, I can't help but doing shallow DOF shots even with a fisheye :LOL:

Understand though, that the 30 isn't a fisheye.

The tulip image is worthy of an enlargement! NICE!

I'm quite sure it is a full frame (rectangular) fish eye lens.
